What Kind of a Payback will Air Sealing Provide?
If up to 40% of residential heating and cooling costs come from air leaks, plugging those leaks can yield significant savings. Instead of spending your money on heat that is going out of the house, why not use the same money to plug the leaks? The more leaks that are plugged, the more money you keep in your pocket.
Since the materials to do an average air sealing job are both simple and inexpensive, air sealing can often pay for itself in cost savings within 6 years[1]. And after you’ve reached the payback period, you continue to save money every year. By comparison, the payback period for new windows – which are often purchased to save energy and money – can be as long as 50 years due to the cost of replacement windows. While those new windows may provide better appearance, more functionality and higher property value, energy cost savings aren’t a primary reason for replacing windows.
